Twelve people who say former Rose Medical Center scrub tech Kristen Parker infected them with hepatitis C asked a federal judge Wednesday to allow them to attend her upcoming blood test, polygraph test and debriefing with prosecutors.

The U.S. Attorney’s Office is opposed to the victims’ attendance at the debriefing and testing.

Prosecutor Jaime Peña has indicated he will allow victims to submit questions to him and he will relay them to Parker.

Jeff Dorschner, spokesman for the Colorado U.S. attorney, said prosecutors have continuously informed the victims since the beginning of the case but can’t allow them into the debriefing and tests.

“It is unprecedented for victims to attend a polygraph and a medical procedure — in this case, the drawing of blood,” he said. “The government is taking the extraordinary step to allow victims to submit questions that could possibly be submitted to the defendant during that interview.”

Additionally, in January, prosecutors are expected to host a meeting for victims to discuss sentencing issues, Dorschner said.

Parker’s attorney, Gregory Graf, does not oppose the victims’ request to attend the debriefing and tests.

“Ms. Parker has agreed to cooperate with the victims including Rose,” Graf wrote in an e-mail response to questions. “Ms. Parker is extremely sorry that her actions have caused anyone harm. Her only remedy is to be truthful and helpful to all involved.”

Parker has pleaded guilty to charges of tampering with and stealing drugs meant for surgery patients and is scheduled to be sentenced Jan. 22.

Prosecutors are recommending a 20-year prison sentence.

Parker is expected to fully debrief prosecutors Wednesday about her crimes, and the motion says a representative from Rose Medical Center is also going to be present during the debriefing and testing.

But Dorschner said that Rose representatives will not be attending the debriefing or the polygraph.

“Rose representatives will not be present, only government investigative-agency representatives, defense counsel and the witness,” he said.

Attorneys Hollynd Hoskins and Jim Leventhal filed the motion seeking access to the testing and debriefing because they believe it is essential to the health and welfare of the victims, and the information could bolster the civil case they have filed against Parker and Rose Medical Center.

“The refusal to allow their participation while conferring with and allowing Rose Medical Center to direct the truth-seeking debriefing of Ms. Parker does anything but honor the actual crime victims’ rights to be treated with fairness and respect,” the motion says.

The attorneys also are seeking disclosure of grand-jury material that the victims believe shows other employees at Rose Medical Center were suspected of stealing drugs.

Grand-jury testimony and evidence are typically considered secret unless introduced later at trial.
